The nutrient line you choose depends on the irrigation you have setup and how involved you want to get with customization. Our 1-Part lines are as easy as it gets. Mix them up at 6-9 grams per 1 gallon of clean water and use it with any substrate.
If you are using injectors or dosatron systems, you will need to use our 3-part line to make liquid concentrates on demand. If you have limited injector space, the Micro and Bloom powders from the 3-part line can be combined and used with Grow to make a simple 2-part (A&B) stock solution.
The most flexibility comes from our 4-part line. The 4-part line can not be made into concentrates and has to be mixed into a standard reservoir. The 4-part line has control over 4 major elements. Grow controls Nitrogen, Ca-mg controls Calcium, Micro controls Iron and Bloom controls Potassium. Custom feeding charts can be made on the New Chart page here on the Perfect Grower website.
